Abstract

Summary

The Spectral Induced Polarization (SIP) method is a useful method to apply as a proxy for the determination of hydraulic parameters. We investigated the influence of heterogeneity in sedimentary laboratory samples and its influence on SIP parameters and hydraulic conductivity. For the measurements we used a specifically designed cell where material can be allocated arbitrarily in samples of 18 cubic decimetres in size under pressurized groundwater conditions. It allows to carry out 4-electrodes SIP and hydraulic measurements on the same sample without disturbing it. In this work we focused on parallel and series samples of sandstone and sand and the applicability of mixing laws in a simplified experimental context. Samples were constructed with varying volume shares of both materials, including samples of only one material which served as reference cases. The results show that the mixing laws can be confirmed experimentally for SIP parameters and hydraulic conductivity. They can help to further understand field measurements in heterogenous sedimentary environments. This indicates that SIP may be used to identify preferential flow paths as well as aquifer heterogeneity.
